改性沸石对电镀废水中Pb^(2+)、Zn^(2+)、Ni^(2+)的吸附

Adsorption of Pb^(2+) 、Zn^(2+) and Ni^(2+) in Electroplating Wastewater by Modified Zeolite Particles

将天然沸石进行处理制备出多孔质改性沸石颗粒。在静态条件下 ,研究了改性沸石颗粒对重金属离子Pb2 +、Zn2 +、Ni2 +的吸附效果及条件。含Pb2 +、Zn2 +、Ni2 +的电镀废水经改性沸石颗粒吸附后 ,废水中Pb2 +、Zn2 +、Ni2

A modified zeolite particle with pore structure was made from natural zeolite. The adsorption effect and conditions of heavy metal ions such as Pb 2+ , Zn 2+ and Ni 2+ by modified zeolite particles were studied under static state. After treated, the contents of Pb 2+ , Zn 2+ and Ni 2+ in electroplating wastewater were prominently lower than discharge standard of China.
